Abstract

The utility model discloses a probe connector, comprising a metal sleeve, a probe shaft and an elastic element, wherein the metal sleeve is provided with an accommodating chamber which runs upwardly through the metal sleeve, the accommodating chamber is divided into an accommodating portion and an accommodating groove from up to bottom, a blocking platform is formed between sidewalls at the connecting position of the accommodating portion and the accommodating groove; the probe shaft is disposed in the metal sleeve, the probe shaft is provided with a shaft body portion, the shaft body portion is provided with a plurality of springs protruding outwardly, and bottom of the probe shaft is provided with a holding portion; and the elastic element is accommodated in the metal sleeve, with one end abutting against the probe shaft. The probe connector can effectively prevent that in usage, poor contact between the probe shaft and the inner wall of the metal sleeve is caused due to shock, causing momentary disconnection, so the probe connector guarantees a stable electric connection.

Description

The probe connector

Technical field

The utility model relates to a kind of connector, relates in particular to a kind of probe connector.

Background technology

The probe connector is a kind of electronic devices and components that are mainly used in the electronic products such as mobile phone, is used for connecting the metallic contact of detachable electrical sub-elements such as battery or smart card, so that battery or smart card can be enabled by electronic product after installing.A kind of existing probe connector comprises a metal sleeve, a needle shaft and a flexible member etc., wherein, usually the needle shaft lower surface is designed to an inclined-plane, when needle shaft is depressed, the flexible member of this inclined-plane in a side pressure receding metal sleeve, and, needle shaft is resisted against on the inwall of metal sleeve to a side, thereby realize electrically connecting by the bounce that flexible member produces.

When above-mentioned existing probe connector in use was given a shock, needle shaft and metal sleeve inwall can come in contact bad and cause hit, influenced circuit and connected.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of stable probe connector that electrically connects that has is provided.

For achieving the above object, the utility model provides the probe connector to comprise a metal sleeve, a needle shaft and a flexible member; Metal sleeve has a host cavity that upwards runs through this metal sleeve, and host cavity is divided into a resettlement section and an accepting groove from top to bottom, is formed with a retaining platform between the sidewall of resettlement section and accepting groove connection; Needle shaft is installed in the metal sleeve, and this needle shaft has an axis body portion, and axis body portion is provided with some shell fragments to outer lug, and the needle shaft lower end has a holding section; Flexible member is contained in the metal sleeve and an end is resisted against on the needle shaft; When needle shaft is pressed into metal sleeve, slide in accepting groove and keep off platform and can keep off and hold the holding section in the holding section, and shell fragment is resisted against on the inwall of resettlement section slidably.

The utility model probe connector is by the design of shell fragment, can prevent from effectively that the probe connector in use is given a shock to make needle shaft and the loose contact of metal sleeve inwall and cause hit, thereby guarantee to electrically connect stable effect.

Embodiment

By describing technology contents of the present utility model, structural feature in detail, realized purpose and effect, give explanation below in conjunction with execution mode and conjunction with figs. are detailed.

See also Fig. 1 and Fig. 2, the utility model probe connector 1 comprises a metal sleeve 10, a needle shaft 20 and a flexible member 30.

See also Fig. 2 and Fig. 3, described metal sleeve 10 comprises a housing 11, housing 11 lower ends are connected with the disc-shaped base 12 of a sealing, the stopper section 13 that housing 11 upper ends bend inwards and extend to form an annular, be formed with an opening 14 in the middle of the stopper section 13, form a host cavity 15 in the housing 11, this host cavity 15 is divided into a resettlement section 151, an accepting groove 152 and an engaging groove 153 from top to bottom, resettlement section 151 diameters are less than accepting groove 152 diameters, thereby are formed with a retaining platform 154 resettlement section 151 is connected the sidewall of device with accepting groove 152 between.

Please continue and consult Fig. 2 and Fig. 3, described needle shaft 20 has a roughly tubular axis body portion 21, one is positioned at axis body portion 21 upper ends and seals being of axis body portion 21 hemispherical contact site 22 and be positioned at needle shaft 20 lower ends and be circular holding section 23, punching press is formed with some shell fragments 24 to outer lug in the axis body portion 21, and needle shaft 20 inside are formed with a storage tank 25 that runs through this needle shaft 20 downwards.

Please consult Fig. 3 again, during the utility model probe connector 1 assembling, flexible member 30 is contained in metal sleeve 10 and the storage tank 25, and flexible member 30 1 ends are resisted against in the engaging groove 153, and the other end is resisted against in the storage tank 25.Needle shaft 20 is installed in the metal sleeve 10, holds holding section 23 thereby holding section 23 diameters can keep off greater than resettlement section 151 diameters retaining platform 154, and makes holding section 23 be limited in slip in the accepting groove 152; Contact site 22 diameters stretch out outside the metal sleeve 10 thereby this contact site 22 can pass the opening 14 of metal sleeve 10 less than opening 14 diameters; When shell fragment 24 slides in resettlement section 151, shell fragment 23 conflict resettlement sections 151 inwalls.

During the utility model probe connector 1 work, the base 12 of metal sleeve 10 is welded in (figure does not show) on the electronic component, the contact site 21 of needle shaft 20 stretches out outside the metal sleeve 10 by host cavity 15, is connected (scheming not show) with another electronic component; When needle shaft 20 owing to being subjected to the external force effect to be pressed into metal sleeve 10, slide in accepting groove 152 in holding section 23, shell fragment 23 is resisted against on 151 inwalls of resettlement section slidably, thereby reaches reliable electric connection.

As mentioned above, the utility model probe connector 1 is by the design of shell fragment 24, can prevent from effectively that the probe connector in use is given a shock to make needle shaft and the loose contact of metal sleeve inwall and cause hit, thereby guarantee to electrically connect stable effect.
